Drinking Water: Extreme Weather Events Threaten Quality, Says Report

The greatest risks to water quality come from cumulative impacts of extreme weather events that happen sequentially, like a drought followed by a wildfire followed by a flood, says joint Australian-US study. As climate change likely increases the frequency of extreme weather events, resilience must be built into the management of watersheds and water treatment systems for recovery to happen.

Report: Society's Water Safety Net Is Fraying

A new National Research Council report examines possible "tipping points" that might occur if the rate of groundwater pumping rapidly increases. As surface water-scarce regions get drier amidst climate change, early warning water and drought monitoring systems could be necessary to protect precious resources. [Circle of Blue]

Losing Ground: Louisiana

In just 80 years, 2,000 square miles of Louisiana's coast has turned to open water, wiping places off maps and posing a lethal threat to an energy and shipping corridor vital to the nation's economy. And it's going to get worse. At the current rates that the sea is rising and land is sinking, NOAA scientists say by 2100 the Gulf of Mexico could rise as much as 4.3 feet across this landscape, which has an average elevation of about 3 feet. If that happens most of Southeast Louisiana would be underwater. [Propublica]

New Report Highlights USA's Water-Supply Woes

A report by Charting New Waters concluded that "diminished water supply is the greatest threat to the economic security and social stability of major portions of this country." According to hundreds of experts, US water problems are common because of leaking infrastructure and poor and inefficient water-use decisions, among others. Solutions are offered, from better valuing water to upgrading and integrating utilities to integrating water, energy and food production. [USA Today]

Fixing Climate Change May Add No Costs, Report Says

A new economic study found that if the world were to adopt an ambitious series of measures to limit greenhouse gas emissions over the next 15 years, it would only cost about 5 percent more than the amount that would likely be spent anyway on new power plants, transit systems and other infrastructure.

GMO Safety, Weed Control Top Concerns as US Study Kicks Off

Concerns around genetically modified (GM) crop safety dominated the first public meeting for a new US-sponsored study underway to examine the impacts of GM crops. Ag experts pointed to pesticide use, weed and insect resistance, and public health issues stating that without solid, third-party evidence for GM safety public mistrust of GM crops will continue. We can't agree more. [Reuters]
